Time Series Analysis Package

This example uses the TSMODEL procedure to compute the seasonal indices of the time series Air:

proc tsmodel data=mycas.air outarray=mycas.outarray;
   id date interval=month;
   var air;
   outarrays sindices;
   require tsa;
   submit;
   declare object TSA(tsa);
   rc=TSA.SEASONALINDICES(air, _SEASONALITY_,  'ADD', 'STQC', sindices);
   endsubmit;
run;
